Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

With the rapid development of display panels, OLED display panels with high screen occupation ratio are becoming more and more the trend of current development, and accordingly, the technology of cameras under screens is also receiving more and more attention from people. The camera technique is about to place the camera in the screen below under the screen, and is different with traditional hole screen technique of digging, and the camera region still remains has complete screen display function, and this has very big promotion to screen display's integrality. In brief, after the camera under the screen is adopted, the partial complete display of the front screen can be realized in the aspect of screen display, the screen display effect similar to the scheme of the pop-up camera is achieved, and the level which can be achieved by the hole digging screen is achieved in the aspects of weight, thickness and the like.

However, in order to ensure the imaging quality of the under-screen camera and improve the light transmittance of the under-screen camera display area, some processing is usually performed on the under-screen camera display area, for example, the pixel density of pixels in the under-screen camera display area is reduced to improve the light transmittance. However, because the brightness of the under-screen camera display area needs to be kept equal to that of other display areas, and the pixel density of the under-screen camera display area is smaller than that of the other display areas, the power consumption of the under-screen camera display area is greater than that of the other display areas. As time goes by, the display luminance of the off-screen camera display area may be more and more different from those of the other display areas. Moreover, high power consumption is accompanied by high losses, and the screen life of the under-screen camera display region is reduced faster than that of the other display regions.

As an alternative implementation of the disclosure, an embodiment of the present application provides a display panel, where fig. 1 is a schematic plane structure diagram of the display panel, fig. 2 is a schematic plane structure diagram of a first display area shown in fig. 1, and fig. 3 is a schematic cross-sectional structure diagram of the display panel shown in fig. 2 along a cutting line AA', and with reference to fig. 1, fig. 2, and fig. 3, the display panel S includes: a first display area S1 and a second display area S2. The light transmittance of the first display area S1 is greater than that of the second display area S2. The display panel includes a base substrate 11 and a light emitting layer 12 disposed on the base substrate 11. At least the first display region of the display panel further comprises a light adjusting layer 13 disposed on the base substrate 11. The light adjusting layer 13 is located on a side of the light emitting layer 12 away from the substrate 11.

The light-emitting layer 12 includes a plurality of light-emitting pixels 121; the light ray adjustment layer 13 includes a light converging layer 131; the light converging layer 131 includes a plurality of opening regions 1311, and an orthographic projection of the opening regions 1311 on the substrate 11 covers at least an orthographic projection of the light emitting pixels 121 on the substrate 11.

The cross-sectional curve of the sidewall of the light converging layer 131 at the opening region 1311 is a preset curve, and the preset curve makes the width of the opening region 1311 gradually increase in a direction away from the substrate 11, so that the sidewall of the opening region 1311 reflects light rays emitted by the light emitting pixel 121 at a preset angle.

Wherein the cross-sectional curve is a curve of the sidewall on a cross section perpendicular to the substrate 11, and the width of the open region 1311 is a width of the open region 1311 in a direction parallel to the substrate 11.

In some embodiments, the light adjusting layer 13 may further include a light refractive index layer 132, the light refractive index layer 132 is located on a side of the light converging layer 131 away from the substrate 11 and fills the plurality of opening regions 1311; wherein the refractive index of the light converging layer 131 is smaller than that of the light refractive index layer 132.

In the present specification, unless otherwise specified, "a plurality" means two or more.

The first display area S1 may be an off-screen camera display area, and the second display area S2 may be a main display area.

The pixel density of the display area of making a video recording under the screen is less than the pixel density of main display area, can guarantee to set up the formation of image effect of the camera under the display area of making a video recording under the screen, improves the luminousness of the display area of making a video recording under the screen, simultaneously, adopts as above display panel' S first display area S1 as the display area of making a video recording under the screen, can effectively promote the luminous efficiency at positive visual angle, improves the light-emitting brightness, and then reduces the consumption, promotes the life of the display area of making a video recording under the screen, improves the problem that the display area of making a video recording shows unequally with main display area under the screen after long-time the use.

The light-emitting layer 12 includes a plurality of light-emitting pixels 121, and the plurality of light-emitting pixels 121 may be arranged in an array in the light-emitting layer 12. The substrate 11 may be a rigid substrate such as a glass substrate or a silicon substrate, or may be a flexible substrate such as Stainless Steel (SUS) or flexible Polyimide (PI). That is, the display panel in the embodiment of the present application may be a rigid display panel that is not bendable, or may be a flexible display panel that is bendable.

As shown in fig. 2 and 3, the curve of the sidewall of the opening region 1311 on the cross section perpendicular to the substrate 11 is a predetermined curve, the light-collecting layer 131 is located on the light-emitting side of the light-emitting layer 12, and the orthographic projection of the opening region 1311 on the substrate 11 at least covers the orthographic projection of the light-emitting pixels 121 on the substrate 11, so that each light-emitting pixel 121 is surrounded by the light-collecting layer 131 based on the opening region 1311, and the sidewall of each opening region 1311 presents a curved surface capable of adjusting the incident angle of more incident light rays.

It is understood that total reflection is an optical phenomenon, and when a light ray enters a medium with a lower refractive index from a medium with a higher refractive index, if the incident angle is larger than a certain critical angle (the light ray is far away from the normal), the refracted light ray will disappear, and all the incident light ray will be reflected without entering the medium with a lower refractive index.

Therefore, as shown in fig. 3, after the light emitting pixel 121 emits light, light firstly enters the light refractive index layer 132 through the opening region 1311, and after being refracted by the light refractive index layer 132, the light with the normal viewing angle is directly emitted, and meanwhile, a part of light with large angles is refracted to the extension of the opening region 1311 of the light converging layer 131, because the refractive index of the light converging layer 131 is smaller than the refractive index of the light refractive index layer 132, the light with the normal viewing angle can be totally reflected to the light with the normal viewing angle through the total reflection of the side wall at the opening region 1311, so that the light emitting efficiency at the normal viewing angle is improved, the power consumption is reduced, and the service life of the display panel is prolonged.

The light with the positive viewing angle is the light which is emitted from the light-emitting pixel and the emergent light is vertical to the light adjusting layer. The light with a large viewing angle is light emitted from the light-emitting pixel and refracted to the light converging layer through the light refractive index layer, and the incident angle of the light converging layer is larger than the critical angle (the incident angle when the refraction angle is 90 degrees).

In fig. 2, the light-emitting pixels 121 are illustrated as being square, but the present invention is not limited to this. In other embodiments, the shape of the light emitting pixels may be other shapes, such as circular, elliptical, rectangular, etc.

In other embodiments of the present application, the sidewall of the light converging layer 131 at the opening region 1311 includes at least two sub-sidewalls, which are sequentially arranged in a direction away from the substrate base plate 11; the cross-sectional curves of at least two of the sub-sidewalls are different. .

As shown in fig. 4, the preset curve is formed by the section curves T1 and T2 of the two sub-sidewalls, wherein the starting point T11 of T1 is the starting point of the preset curve, i.e. the sidewall point at the minimum width of the opening region 1311; the end point T12 of T1 is connected to the start point T21 of T2, and the end point of T2 is the end point of the predetermined curve, i.e., the sidewall point at the maximum width of the opening region 1311. The preset curve is formed by the cross-sectional curves of at least two sub-sidewalls, so that the limitation of the sidewall of the opening region 1311 in a single shape on the angle of the incident light can be avoided to a certain extent, the incident angle of the incident light from the light refractive index layer 132 can meet the requirement of the incident angle of total reflection, and the incident light is totally reflected by the sidewall of the opening region 1311 to a greater extent to be the light of a normal viewing angle, thereby further improving the light-emitting brightness.

It is noted that the cross-sectional curves at different positions can be adjusted based on the principle of total reflection of light to obtain a better light rendering effect.

In other embodiments of the present application, the sidewall of the light converging layer 131 at the opening region 1311 may include three sub-sidewalls, and as shown in fig. 5, the cross-sectional curves of the three sub-sidewalls may sequentially include a first cross-sectional sub-curve J1, a second cross-sectional sub-curve J2, and a third cross-sectional sub-curve J3, that is, the preset curve is formed by three segments of curves J1, J2, and J3.

In order to make the light converging layer 131 have an excellent improvement ratio on the normal viewing angle, a simulation test of total reflection of light rays can be performed by using a first cross-section sub-curve J1, a second cross-section sub-curve J2 and a third cross-section sub-curve J3, and a first formula, a second formula and a third formula are obtained through calculation, where the first cross-section sub-curve J1 can satisfy the first formula, the second cross-section sub-curve J2 can satisfy the second formula, and the third cross-section sub-curve 3 can satisfy the third formula.

Specifically, the first formula is:

y＝0.7241x ³ +0.8171x ² +0.1096x,0＜x＜0.624 (1)

the second formula is:

y＝-0.1672x ⁴ +1.284x ³ -3.8245x ² +5.8629x-1.8754,0.624≤x＜2.519 (2)

the third formula is:

y＝-0.0006x ⁴ +0.0189x ³ -0.2266x ² +1.2109x+0.5181,2.519≤x≤10.2 (3)

where x is an abscissa of any point on the cross-sectional curve, y is an ordinate of any point on the cross-sectional curve, the abscissa represents a half of a difference between the width of the open region 1311 at the point and the minimum width of the open region 1311, the ordinate represents the height of the open region 1311 at the point, and the height of the open region 1311 is the length of the open region 1311 in a direction perpendicular to the substrate 11.

It should be noted that, in some embodiments of the present application, only the preset curves include the first cross-section sub-curve J1, the second cross-section sub-curve J2, and the third cross-section sub-curve J3, and the first cross-section sub-curve J1, the second cross-section sub-curve J2, and the third cross-section sub-curve J3 respectively satisfy the above formula (1), formula (2), and formula (3), for example, but the present application is not limited thereto, and in other embodiments, the first cross-section sub-curve J1, the second cross-section sub-curve J2, and the third cross-section sub-curve J3 may also respectively satisfy other curve formulas, and the preset curves may further include more cross-section curves.

In some embodiments of the present application, as shown in fig. 6, fig. 6 is a schematic cross-sectional structure diagram of a display panel provided in another embodiment of the present application, and the display panel S may include a plurality of light adjustment layers 13 stacked in layers.

Among the plurality of light adjustment layers 13, the shape of each light adjustment layer 13 may be the same or different. At least two layers of light adjusting layers 13 are arranged in the direction N perpendicular to the substrate base plate 11, and compared with a single layer of light adjusting layer 13, more incident light can be totally reflected into light with a normal viewing angle, and the light emitting efficiency is greatly improved.

Of course, in order to further improve the light extraction efficiency, the minimum widths of the open regions 1311 of the plurality of light converging layers 131 may be sequentially increased in the direction N away from the substrate 11. As shown in fig. 6, of the two corresponding opening regions 1311a and 1311b of the adjacent light adjustment layers 13a and 13b, the width of the opening region 1311a close to the light-emitting layer 12 is L1, the width of the opening region 1311b far from the light-emitting layer 12 is L2, and the minimum value of L1 may be smaller than the minimum value of L2, that is, the minimum width of the opening region 1311a is smaller than the minimum width of the opening region 1311 b. Thus, on the basis of the first light adjustment layer 13a, the second light adjustment layer 13b is added, and the opening width in the second light adjustment layer 13b is increased, so that part of the light which is not totally reflected to the front viewing angle by the sidewall at the opening region 1311a of the first light adjustment layer 13a can be totally reflected to the front viewing angle by the sidewall at the opening region 1311b of the second light adjustment layer 13 b. Therefore, the light emitting efficiency can be further improved, and the power consumption is reduced.

In still other embodiments of the present application, referring to fig. 6, the display panel S may include a first light converging layer 131a and a second light converging layer 131b sequentially arranged on the base substrate 11.

Wherein the minimum horizontal distance from the sidewall of the first light convergence layer 131a at the opening region 1311a to the corresponding light emitting pixel 121 is 0; the minimum horizontal distance of the sidewall of the second light convergence layer 131b at the opening region 1311b to its corresponding light emitting pixel 121 is in the range of 0.5 to 2 μ M, and the horizontal distance is a distance in a direction parallel to the substrate 11, i.e., a distance in the direction M.

When the light adjustment layer 13 is two layers, simulation test is performed on the light path, as shown in fig. 7 and 8, fig. 7 is a comparison graph of the effect of the height of the second light adjustment layer 13b relative to the height of the first light adjustment layer 13a and the improvement ratio of the front-view-angle light emission luminance. Wherein, W, R, G and B respectively correspond to a white light sub-pixel, a red light sub-pixel, a green light sub-pixel and a blue light sub-pixel in the luminous pixel; the X-axis is the height of the second light adjustment layer 13b relative to the first light adjustment layer 13a, and the Y-axis is the improvement ratio of the front-view-angle light emission luminance. As can be seen from the figure, the higher the height of the second light adjustment layer 13b is relative to the height of the first light adjustment layer 13a, the greater the improvement ratio of the front-view-angle luminance of the light. The improvement ratio of the front-view-angle light emission luminance refers to a ratio of the front-view-angle light emission luminance of the display panel including the two light adjustment layers 13 to the front-view-angle light emission luminance of the display panel not including the light adjustment layers. Fig. 8 is a graph comparing the effect of the distance d between the sides of the opening regions 1311b of the second light adjustment layer 13b in the direction M parallel to the substrate 11 and the improvement ratio of the front-view-angle light emission luminance. Wherein, W, R, G and B respectively correspond to a white light sub-pixel, a red light sub-pixel, a green light sub-pixel and a blue light sub-pixel in the light-emitting pixels; the X-axis is the distance d, and the Y-axis is the improvement ratio of the light emitting brightness at the front view angle. As can be seen from the figure, when the distance d is 0.5 to 2 μm, the improvement ratio of the light emitting luminance at the front viewing angle is large, and when d is 1.5 μm, the light emitting effect of the display panel is better, therefore, the distance d may be preferably 1.5 μm.

In some embodiments of the present application, there are many possibilities for the shape of the light-emitting pixels 121 in the light-emitting layer 12, and in order to improve the light extraction efficiency of the display panel, the shape of the orthographic projection of the opening region 1311 on the substrate 11 may be the same as the shape of the orthographic projection of the light-emitting pixels 121 on the substrate 11. That is, when the shape of each pixel 121 is circular, the shape of the orthogonal projection of the pixel on the substrate 11 is also circular, and the shape of the orthogonal projection of the corresponding opening region 1311 on the substrate 11 is also circular.

In some embodiments, the size of the orthographic projection of the opening region 1311 on the substrate 11 is greater than or equal to the size of the orthographic projection of the corresponding light-emitting pixel 121 on the substrate 11.

Of course, the present application is not limited thereto, and in other embodiments, the shape of the orthographic projection of the opening region 1311 on the substrate 11 may be different from the shape of the orthographic projection of the light-emitting pixel 121 on the substrate 11. For example, the shape of the orthographic projection of the opening region 1311 on the substrate 11 is circular, the shape of the orthographic projection of the pixel 121 on the substrate 11 is square, and the circle covers the square.

In some embodiments of the present application, the material of the light converging layer may be OCA glue; the material of the light refractive index layer may be zirconia. Of course, the present application is not limited thereto, and in other embodiments, the material of the light converging layer and the material of the light refractive index layer may also be other transparent materials.

In some embodiments of the present application, as shown in fig. 9, the display panel may further include an encapsulation layer 14, where the encapsulation layer 14 is located between the light emitting layer 12 and the light adjusting layer 13, and plays a role in isolating water and oxygen, and encapsulating.

The encapsulation layer 14 may be a single layer or multiple layers, and may be formed by chemical vapor deposition or inkjet printing.
